HAVANA (AP) — The Arkansas Game and Fish Commission said about 3,000 fish have been found dead on the Petit Jean River near Blue Mountain Lake.

The commission said the fish kill was located near the Logan-Yell county line in western Arkansas.

Officials said it appears the combination of high water temperatures, numerous fish in the pool below the lake’s dam and low dissolved oxygen levels in the water contributed to the kill.

Commission biologists have been monitoring the species and fish size of the kill. District Fisheries Biologist Bob Limbird said there was a large number of fish in a small area and too much oxygen demand by too many fish combined with the hot water.

Most of the fish were gizzard shad, sunfish, freshwater drum, minnows and crappie.
